This upper radiator hose is a vital part of the engine's cooling system, facilitating the flow of coolant between the engine and the radiator. Constructed from durable, heat-resistant rubber, it ensures reliable operation under high temperatures and pressures, unlike a collapsed or leaking hose. Symptoms of a failing hose include visible cracks or bulges, coolant leaks around the connection points, or engine overheating.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing upper radiator hose is often a visible bulge or softening of the rubber, or a persistent coolant smell. If left unaddressed, the hose can rupture under pressure, leading to a rapid loss of coolant and severe engine overheating. This can result in significant engine damage if the machine is operated without proper cooling.
Ensure the hose clamps are positioned correctly over the designated hose bead or groove on the pipe to prevent leaks. Do not reuse old hose clamps, as they may not provide adequate or even pressure.
Inspect the lower radiator hose and thermostat for signs of wear or malfunction when replacing the upper hose.
